Question

A cube is coloured red in all face it is cut into 64 smaller cubes of equal size

Answer 1

simple
in total it will become 4×4×4 =64
ie , L×B×Hpainted on three sides = 8
2 side = 2×12 =24
1 side =5×6 = 24
then 24+24+ 8 will become 56
it means that the cubes painted with no side will be 64- 56 =8
the answer is 8
